First private key is corresponding with video capture device.Again by enciphered video data and the first signature transmission to accepting terminal.This
Sample, accepting terminal can verify the first signature by the first public key corresponding with the first private key, to verify video capture device
Identity.After the first signature verification passes through, accepting terminal can be decrypted in local security region by symmetric key, with
To video data.After accepting terminal decrypts to obtain video data, can extract from video data includes biological nature
Picture frame is as biometric image.
In one embodiment, accepting terminal can detect the picture frame for including in video data, when in picture frame
There are when biological characteristic, using the picture frame of acquisition as biological characteristic figure.For example, accepting terminal can be examined by taking facial image as an example
It surveys with the presence or absence of facial image in the picture frame, facial image, then obtain the picture frame as facial image if it exists.At one
In embodiment, when the camera of video capture device is 3D camera, the picture frame of video capture device acquisition includes one by one
Corresponding depth map and cromogram, accepting terminal can will include biological characteristic and corresponding depth map and cromogram are common
As biometric image.
It is the schematic diagram of key exchanged form in one embodiment with reference to Fig. 3, Fig. 3.In one embodiment, it is regarded to ensure
Confidentiality of the frequency evidence in transmission process, video capture device and accepting terminal can be intercoursed asymmetric in production environment
Public key, to complete the two-way authentication between video capture device and accepting terminal.Wherein, production environment refers to that equipment is sold investment and made
With the preceding stage.In one embodiment, respective public key can be also uploaded to verifying clothes by video capture device and accepting terminal
Business device, verifies identity for authentication server.In this way, video capture device and accepting terminal are carrying out data transmission respectively
When, so that it may it is signed by respective private key, in this way, data receiver can ensure data source by verifying signature
Reliability.
Correspondingly, authentication server can issue symmetric key to accepting terminal, and symmetric key is transmitted to by accepting terminal again
Video capture device.In this way, video capture device can be encrypted video data by the symmetric key, accepting terminal
It can be decrypted to obtain video data by the symmetric key in local security region, ensure that video data is being transmitted across
Safety in journey.When the biological information of extraction is transmitted to authentication server by accepting terminal needs, accepting terminal can
Biological information is encrypted to obtain encrypted feature information by the symmetric key issued, encrypted feature information is transmitted to
Authentication server has ensured safety of the biological information in transmission process.
It is appreciated that the symmetric key can be what server issued, it is also possible to accepting terminal or video capture device
It is transmitted to other equipment after generation, only need to ensure that each equipment can be carried out safe data communication, the embodiment of the present application
In do not limit this.It is further appreciated that video capture device and accepting terminal can share the first symmetric key, video acquisition is set
Standby to pass through the first symmetric key encryption, accepting terminal passes through the first symmetric key decryption.Accepting terminal and authentication server are shared
Second symmetric key, accepting terminal pass through the second symmetric key decryption by the second symmetric key encryption, authentication server.Its
In, the first symmetric key and the second symmetric key specifically can be identical symmetric key, be also possible to different symmetric keys.
In above-described embodiment, video capture device is by the video data encrypted transmission of acquisition to accepting terminal, accepting terminal
Biometric image is obtained after decrypting in safe zone, in this way, using encryption safe between video capture device and accepting terminal
Transmission mode can guarantee biometric image not by man-in-the-middle attack and leakage, and accepting terminal is in safe zone to adding
Close video data is decrypted, and is greatly improved the safety of authentication.
S204 extracts the biological information in biometric image in local security region.
Wherein, local security region is the safety zone of accepting terminal local, and the operation carried out in safe zone is peace
Full operation.Safety zone (Trusted Execution Environment, abbreviation TEE), also referred to as secure and trusted area
Domain, TEE are isolated from REE (Rich Execution Environment, fly-by-night execution region, also referred to as general areas),
External computer device can only be communicated by specific entrance with TEE.Thus, it is extracted in accepting terminal local security region
Biological information in biometric image is a kind of safe and reliable operation, can ensure to the process of biological characteristic processing and
As a result safety.
Biological information is the information for reacting biological characteristic, can be used for carrying out authentication.Biological information is specific
It can be from colouring information relevant to biological characteristic, texture information and shape information extracted in biometric image etc.
One or more of combinations.For example, the coordinate information of biological characteristic point, reflect biological characteristic pixel color Distribution value and
Pixel brightness Distribution value and the pixel depth of biometric image etc..
It is illustrated by taking facial image as an example, when biometric image includes facial image, accepting terminal is from face figure
The biological information extracted as in specifically may include face location information.Wherein, face location information refer to face profile,
The distance between each face's organ such as hair style, ear, eyes, nose, mouth or the information for positioning coordinate.Such as two eye distance from,
Nose and eye-angle, alternatively, mouth and nose distance etc..
It is illustrated by taking fingerprint image as an example again, accepting terminal can take the fingerprint streakline in image in local security region
With the information of line type, wherein line type is that the regular arrangement of streakline is formed by.The biological information of fingerprint image for example,
Starting point, terminal, binding site and bifurcation of streakline etc..
Specifically, biometric image can be transmitted to local security area after obtaining biometric image by accepting terminal
